Cameroon headed home from Brazil after losing all three games against Mexico, Croatia and Brazil to finish bottom of Group A.

The FECAFOOT statement read: "Recent allegations of fraud around Cameroon 2014 FIFA World Cup three preliminary games, especially Cameroon vs. Croatia, as well of the "existence of seven bad apples [in our national team]" do not reflect the values and principles promoted by our administration, in line with FIFA Code of Conduct and the ethics of our nation.

"We wish to inform the general public that, though not yet contacted by FIFA in regards to this affair, our administration has already instructed its Ethics Committee, to further investigate these accusations.

"We are strongly committed to employ all means necessary to resolve this disruptive matter in the shortest delays.

"In the meantime we legitimately request that any related information, unless brought before our federation and/or its Ethics Committee, be held for or treated as mere assumption.

"We wish to reinstate that in fifty-five (55) years of existence, FECAFOOT has never been sanctioned for, involved in, or even linked to match fixing or any fraud of any kind."

The allegations came from convicted fraudster Wilson Raj Perumal, who had correctly predicted the 4-0 result and that a player would be sent off in a discussion with German magazine Der Spiegel.
